1. Summary of the impact

Accelerator research is of great value to science, society and industry, but this technology does not traditionally feature in mainstream media, nor is it part of school curricula. Public awareness of how accelerators work therefore remains low despite their importance. To address this challenge, the QUASAR Group at the University of Liverpool has taken a novel approach to public engagement to make the benefits of its research accessible and understandable.

The wide-ranging outreach activities and strategic communication have engaged millions of people around the globe, improved public understanding of accelerator science, triggered public debate and set best practice for science communication. Innovative workshops and events have educated new and underrepresented audiences, raised young people’s aspirations towards science, and created award-winning educational content for visually impaired children.

2. Underpinning research

The research that underpins this impact case study has been carried out in the University of Liverpool’s Quantum Systems and Accelerator Research (QUASAR) Group, based at the Cockcroft Institute – an international centre of excellence in accelerator science and technology that was founded 2006. The QUASAR Group, founded by Professor Welsch in 2007, develops and optimizes particle accelerators, light sources and related technologies, with a focus on novel beam diagnostics. Present research includes: frontier accelerators - LHC and its upgrade and Future Circular Collider (FCC); novel accelerators - laser- and beam-driven plasma wakefield accelerators; accelerator applications - medical applications and beam instrumentation.

Prof Welsch and Dr Edmonds are the key researchers in this impact case. Their research has:

  • Developed novel instrumentation solutions based on supersonic gas jets to measure the profile of the HL-LHC beam [3.1].

  • Contributed to an international effort that led to the first demonstration of proton beam crabbing and helped optimize the design of future facilities [3.2].

  • Developed new instrumentation to measure 3D electrostatic field distributions in low energy antiproton and ion experiments, performed simulations into beam transport and tracking, optimized the FLAIR, AD and ELENA facilities, designed new experiments [3.3].

  • Demonstrated first proton-driven acceleration of electron beams, as part of the AWAKE collaboration; Prof Welsch is the scientific project manager of AWAKE-UK and leader of the UK beam diagnostics work package. His research has targeted improved monitors for a full characterization of the electron beam, as well as underpinning simulation studies [3.4].

  • Successfully developed high-energy physics detectors into stand-alone beam monitors that give access to online monitoring of proton and ion beams used in cancer treatment [3.5].

  • Used beam physics and instrumentation expertise to assist the continuous improvement of national and international accelerator facilities [3.6].

Professor Welsch has also initiated and coordinated the EU-funded networks LA³NET (Laser Applications at Accelerators), oPAC (Optimization of Particle Accelerators), OMA (Optimization of Medical Accelerators) and AVA (Antimatter Research) in this REF period. These have attracted 18M EUR of funding, linked 106 academic and commercial institutions, and launched the careers of 72 Fellows with a considerable future impact for science and the economy.

4. Details of the impact

Particle accelerators are wide-ranging in their applications and indispensable for society: They are at the heart of cancer treatment, and drive forward the frontiers of fundamental scientific knowledge. However, public understanding of the technology and awareness of UK research remains low. The University of Liverpool, together with the Cockcroft Institute and partners, is a hotbed of world-class accelerator science research. As coordinator of four large international research and training networks and a key contributor to major European accelerator R&D projects, the QUASAR Group is in a unique position to communicate globally its interdisciplinary research results, as well as the importance of accelerator science in society.

Since August 2013, a strategic outreach and public engagement programme based on the Group’s research has inspired and educated audiences from diverse backgrounds across the UK, Europe, Asia and the Americas; improved awareness of accelerator science in new and underrepresented groups; enthused young people to engage in science; supported public debate, and communicated accelerator science to industry. A range of tactics were used to great effect: workshops, events, teaching resources, films, media relations.

Award-winning workshops: World’s first Tactile Collider “ an opportunity for children with sight loss to feel excited and empowered to pursue a career in science” [5.1]

Tactile Collider - an immersive workshop for visually impaired (VI) children co-created and delivered by Dr Edmonds - has revolutionized the way they learn about accelerators by using soundscapes and specially developed tactile objects to make the physics accessible.

There are around 5,500 VI children in England and Wales aged 12-18. Since 2017, Tactile Collider has reached around 30% of them, directly engaging 286 children and through training of 124 specialist teachers in the Tactile Collider material extending its impact by an estimated further 1,300 VI children. When participants were asked about the impact of the workshop, 50% reported increased confidence talking about physics, 73% said they’d learned something new, and 69% felt inspired to learn more [5.2].

In 2019, Tactile Collider was awarded the European Physical Society’s HEPP Outreach Prize for “outstanding outreach achievement as a unique project” and the Royal National Institute of Blind People (RNIB) See Differently Award for Innovator of the Year [5.1].

International media coverage endorsed quality, e.g. Symmetry Magazine and CERN Courier, radio appearances on In Touch on BBC Radio 4 and a monthly podcast on RNIB Connect Radio since 2019 [5.2]. To raise public awareness of the challenges that affect people with VI and to promote the concept to wider audiences, Tactile Collider was invited to demonstrate at major international cultural and science events, including BlueDot Festival (2017, 2018), Africa Oyé (2018), North West Big Bang (2018, 2019) and CERN Open Days (2019) [5.2].

Engaging events: “ bringing the science to life” [5.2]

Prof Welsch and his Group designed, organized and delivered four large-scale science outreach symposia, three ‘Physics of Star Wars’ events, and eight ‘Accelerator Experience Days’ in the North-West of England. All events were based on Liverpool’s accelerator science research, featured engaging talks and hands-on demonstrations that explained Liverpool research, promoted interaction with scientists and sparked global media interest.

The Ogden Trust’s CEO found “The innovative combination of in-person attendance, online streaming and additional media activity has given these events an exceptionally wide reach and created impressive impact. In addition, teachers reported positive changes in attitudes to pursuing physics further, both at university and beyond.” [5.3]

Outreach symposia engaged a total of 893 high school and college students and 81 teachers from Liverpool City Region in 2015, 2018 and in March and June 2019 in the Arena and Convention Centre. The March 2019 event welcomed almost 1,000 participants, including high school students and their teachers, undergraduate students, scientists and industry, making it one of the largest accelerator science events ever held in England. High profile speakers including former CERN Director of Accelerators, Prof Steve Myers, and EPS Outreach Prize winner Dr Kate Shaw gave live-streamed talks about projects the Group is involved in.

  • Symposia engaged pupils and teachers with the Group’s research and improved their interest in science: “Accelerators are involved in everyday life and students don’t know about that. We’ve come away feeling inspired and excited about physics,” said Mossland’s STEM Coordinator after the 2018 symposium. Another teacher said: “The symposium also offered a good way for me to gain experience and continuing professional development” [5.2].

  • March 2019 symposium was the first-ever VI-inclusive accelerator science event by including Tactile Collider and using a narrator who explained all visual content via Bluetooth headsets to 14 VI young people. “A lot of people can feel daunted by particle physics, but it is possible to make complex ideas accessible and the kids come away feeling like they’ve achieved something”, said a science teacher of VI pupils attending the symposium [5.2].

  • New industry audiences engaged through repeat sector-specific media coverage about the symposia, e.g. Laboratory News, E&T Magazine, Science Business, Technology Networks, AZO Optics [5.4]. New Electronics editor found: “The blend of science and its application in these articles has helped to widen access to information about accelerators as a key underpinning technology for industry and society. (...) Professor Welsch is my ‘go to’ person for opinions and in-depth information about this fascinating subject.“ [5.5]

  • New 3M EUR Future Circular Collider Innovation Study, coordinated by CERN, highlighted the March 2019 symposium as an exemplary event for community engagement [5.6].

Physics of Star Wars events, developed by Prof Welsch and delivered annually 2017-2019, use the iconic films to explain applications of his accelerator R&D to science, society and commerce, improving public awareness and understanding of this technology. They inspired 323 secondary pupils, 22 teachers, 356 members of the public [5.2] and millions via media coverage [5.4].

  • Impact is shown through positive feedback from pupils and teachers: “We had a fantastic time – there are a number of students who’ve been enthused to consider physics at degree level in the future”, said the Head of Science at Heath School [5.2].

  • Interest in science was improved: "I was extremely impressed… being from a single sex (girls) school it is vital that our pupils are able to visualize themselves in STEM subjects,” said a physics teacher at Prenton High School for Girls. “Our pupils talked about their experience with others within their peer group; many pupils from the year group came to ask when it could be run again so they could attend!” The headteacher from St Gregory’s High School added that the events “enhance[d] interest in particular accelerators and the role of CERN (...) They are a magnificent way of not only improving learning but also to build bridges with Liverpool University and raising aspirations.” [5.2]

  • Significance is further evidenced through subsequent invitations to deliver ‘Physics of Star Wars’ for example at Manchester Science and Industry Museum’s Science Late, Daresbury Lab’s Talking Science, Lymm summer festival, and at Barnsley Museums.[5.2]

  • The events created awareness about Liverpool accelerator research around the world through multiple appearances in local TV; UK and US radio stations; national and international press, including Cordis (EU), BBC Science Focus, Total Film and New Electronics (UK), Frankfurter Rundschau (Germany), Gazete Duvar (Turkey), La Nacion (Argentina), National Interest Magazine (USA) [5.4].

Accelerator Experience Days , held by the Group in 2016 and 2017 to inspire young people to consider a career in STEM, engaged 277 year 9 and 10 secondary school children and 22 school teachers from across North West England with Liverpool’s research [5.2]. Impact is demonstrated through feedback, re-use of resources, media coverage, invitations to speak.

  • Over 97% of the school children found the workshops ‘informative’ and 93% ‘interesting’. “I have learned about magnetic fields, antimatter, electric forces and energy, as well as particles and matter. I really saw the fun side of science and felt eager to learn more and try new things.”, “They (the experiments) made me more interested in physics.”, commented pupils who attended the workshops [5.2].

  • “*These workshops gave students an important opportunity to learn about the practical applications of particle accelerators in society, while testing their experimental skills.*” commented the STFC magazine Fascination [5.2].

  • Videos of experiments and explanations of the setups used in the workshops have created an educational resource for pupils and teachers with 67,012 views and 92.5% positive rating on YouTube (5/11/2020) [5.7].

  • Quality is evidenced through invitations to present novel approach e.g. in BBC Radio Manchester and IOP’s Interact symposium (2017); re-use of setups developed for the workshops at other events, including “Coder Dojo” at Beamont Collegiate Academy (2017) and “Small particles, big machines” exhibition in Berlin (2017). [5.2]

Teaching resources: enhancing science education

Science education was enhanced more widely by publishing the educational videos, teaching resources and material from Liverpool’s outreach events to explain accelerator R&D in teaching magazines such as Science in School, Education Technology, and Teaching Times [5.4]. These have provided “an additional reference point for further reading for both pupils and staff.”, said a teacher from Warrington [5.2].

Resources also included acceleratAR, an augmented reality app developed by Dr Edmonds that uses paper cubes to create a virtual accelerator that helps students to learn about accelerator science. The app has been downloaded almost 5,000 times since February 2019 [5.2] and has received excellent reviews from scientific press and was listed as favourite science app by BBC Focus and Popular Science [5.2].

The quality of our educational material is further evidenced by feedback from the publisher of Teaching Times: “We would be very interested in getting more articles of the same sort in the future. It was great the way the article linked serious science with popular culture.” [5.2].

Award-winning films: improving public understanding and supporting public debate

Prof Welsch has co-created four critically acclaimed short films about antimatter ‘ AVA - Nature (anti)matters’ and collider facilities ‘ Future Circular Collider’, ‘ Science knows no Borders’ and their applications ‘ Busy bees and mighty magnets’ with CERN (2018-2019) to showcase accelerator R&D at Liverpool and its partners. The films feature Prof Welsch, other Liverpool staff and Liverpool University campus, as well as collaboration partners, Nobel Laureate Peter Higgs and former CERN Director-General Rolf-Dieter Heuer. Reach and significance is demonstrated through awards, views, feedback, third party endorsement, and re-use:

  • Awards: ‘Future Circular Collider’ - 2020 w3 Silver Award; ‘Science knows no Borders’ - shortlisted for 2019 EVCOM Award [5.1].

  • ‘AVA - Nature (anti)matters’ selected by EU as excellent communication practice, shown to 232 coordinators and managers from 147 networks in 2018 ITN Coordinator’s meeting [5.7].

  • 647,905 total views (5/11/2020), positive rating of 98% from 6.318 engagements [5.7].

  • ‘AVA - Nature (anti)matters’ was the most viewed film out of 380 projects on the EU’s official science short film playlist [5.7].

  • Social media re-posts, positive comments and endorsements from science influencers such as Professors Jim Al-Khalili “very inspirational” and Brian Cox “this is brilliant!” [5.7].

  • Widely shown at major science events: FCC Week (Amsterdam 2018, Brussels 2019), Der Code des Universums (Vienna, 2018), as well as by the Royal Institution (London, 2019), and learned societies such as the IOP.

  • Supporting global debate about the future of high energy colliders: Video snippets and imagery of “Future Circular Collider” re-used by media outlets in the UK, Germany and USA, including BBC, NBC, Guardian, Nature, London Science Museum and leading science portal Seeker, reaching over 1 million people through film, online and print media [5.4], [5.7].

Nature Physics chief editor described ‘Future Circular Collider’ as “clear, engaging and inspiring [that] has been used across different media platforms during a global public debate” [5.8].

Media engagement: bridging the knowledge gap with storytelling

The Group worked with mainstream and scientific media on stories for science-engaged and general audiences in the UK, Europe and the Americas e.g. ‘ Plugging the skills gap’; ‘ What’s the (anti)matter?’; ‘ What have particle accelerators ever done for us?’; ‘Do you want to boldly go where science has not gone before?’. Coverage by BBC Radio 5 Live, BBC’s Naked Scientists, The Times, Times Higher Education and New Statesman (UK), IFL Science (USA), Horizon Magazine and EU Research Magazine (EU), Die Welt (Germany), and BBC Mundo (Spanish-speaking world) improved awareness of Liverpool’s accelerator R&D and the projects the group is involved in for broad, media-engaged public [5.4].

Articles in scientific and technology press for science-inclined public, including Scientific American (USA), New Scientist, New Electronics, BBC Science Focus, Laboratory News, Physics World, UKSPA Magazine, Materials World, Haynes Manual - LHC (UK), Science (EU), and CERN Courier deepened knowledge about the Group’s technology developments [5.4].

Success is evidenced through invited talks about accelerator R&D at events outside academia, including IET workshops (2016, 2018); Lab Innovations - the UK's largest annual exhibition for the laboratory industry - (2018); International Festival for Business (2016). The curator at Lab Innovations said: “There were not many accelerator scientists at the show, everyone that heard Carsten speak will now absolutely be aware of the wide variety of different applications... especially in the medical field.“ [5.9] Quality in stimulating public interest in accelerator R&D is demonstrated by Prof Welsch being appointed as communication lead for the Cockcroft Institute (since 2015), the EU Design Studies EuroCirCol (coordinated by CERN) and EuPRAXIA (coordinated by DESY).

Success story: best practice in accelerator science communication

The significant impact of Liverpool’s public engagement has been recognised by invitations to speak about the communication activities at international events including ESOF (2014), Europe’s largest interdisciplinary meeting on science and innovation, and UKRO national training days (2017) [5.2].

Formal project evaluations have commended the communication and outreach as “ exemplary” and “outstanding in disseminating project results to the general public”. The Cockcroft Institute’s external Advisory Committee found in its 2018 report that the “communication initiatives continue to be impressive and exceptional” and highlighted them as “world-leading”. The European Commission has identified the accelerator science communication as a “success story” and invited Prof Welsch to present his approach in Brussels to project coordinators from across Europe [5.6].

To guarantee sustainability of the Group’s public engagement activities, the Fellows in Liverpool’s accelerator training networks and the Group’s staff and PhD students followed a science communication training programme developed by Prof Welsch. This created more than 100 accelerator science ambassadors, engaging with schools and the public around the world, including India, Mexico, Ukraine and all across the EU, consulting ministries in their home country about accelerator science, creating innovative social media platforms and blogs [5.2]. They continue to help raise awareness about accelerator research and Liverpool’s projects on a global scale.

1. Summary of the impact

Through Liverpool University’s research at CERN’s LHCb experiment, Prof Shears has created an awareness and improved public understanding of cutting-edge particle physics for audiences worldwide through art, philosophical debates, and international media. Impacts include:

  • influenced artistic practice and co-developed a touring Arts at CERN art exhibition visited by 199,996 people at galleries in the UK, Spain, Belgium, Taiwan, and Estonia;

  • shaped public debate and stimulated public interest in particle physics research through debates on Radio 4 and at ‘ the world’s largest philosophy and music festival’, and the creation of a BBC documentary and animation recommended by the British Portrait Gallery;

  • created awareness and improved public understanding of LHCb research across the UK, Europe, and North America through high-profile print, radio, and broadcast media coverage that “ reached audiences of many tens of millions of people”, including: Financial Times, The Guardian, New Scientist, RTÉ Radio, BBC World Service, ITV News, and BBC Breakfast.

2. Underpinning research

Based at CERN, the European Organization for Nuclear Research, the Large Hadron Collider (LHC) is the most powerful particle physics facility ever constructed. LHC data provide the sole source of our knowledge of the elusive Higgs Boson and allow the investigation of matter and antimatter differences (CP violation), Dark Matter and other phenomena that cannot be explained by our current understanding of particle physics, encapsulated in a theory termed the Standard Model. Each of these topics is of outstanding importance to our knowledge of fundamental physics and the structure of the universe. Four main experiments are based at the LHC: ATLAS, CMS, LHCb and, ALICE. STFC coordinates and manages the UK’s involvement and subscription with the LHC at CERN – the UK’s national laboratory for particle physics.

Comprised of 23 academic researchers, the Liverpool Particle Physics Group have been members of the LHCb and ATLAS collaborations throughout the REF period. Shears leads the Liverpool LHCb group which currently consists of five academics, four postdoctoral researchers and six PhD students. Shears established the field of electroweak physics on LHCb and previously led the relevant LHCb physics working groups. She convened the LHC Electroweak Working Group (2011-2020) and Precision Electroweak Working Group (2017-2020) that together span all LHC experimental and theoretical physicists at CERN. Besides performing Standard Model analyses [3.1], the Liverpool group has research interests that span CP violation and rare decay physics (Hutchcroft). The group designed, constructed, commissioned and maintained the VELO particle detector (Bowcock) which provided the data necessary to perform all LHCb physics analyses in this REF period. Shears plays a key role in communicating the results from Liverpool’s research on the LHCb experiment at CERN to audiences worldwide through the Arts at CERN program, philosophical debates, and international media engagement.

Notable particle physics research breakthroughs took place during the REF period as a result of Liverpool’s LHCb research that were covered extensively by international media, including:

  • The first observation of CP violation in charm decays [3.2]: CP violation is a major open question in particle physics. So far it has only been possible to study it by looking at differences between quark and antimatter quark behaviour. Differences have been seen previously in two of the six quark types. LHCb showed that there are also differences in charm quarks, a third type, providing a new laboratory for effects to be studied in. The analysis is only possible thanks to the precision measurements of the VELO detector that the Liverpool particle physics group designed, constructed, commissioned and maintained.

  • Intriguing Standard Model discrepancies in lepton universality measurements [3.3]: the idea that all lepton types should behave in the same way (“universality”) is a cornerstone of the Standard Model. However, lepton universality can be broken if new, unseen particles interfere with normal particle decays. LHCb has observed differences compared to Standard Model predictions, hinting at the existence of new particle interference. If true, this provides the first pointer to a deeper and more fundamental understanding of the universe. The measurement was only possible thanks to the Liverpool-built VELO detector. Recent measurements also rely on the Liverpool group’s electron efficiency data.

  • The observation of new baryon and pentaquark states [3.4, 3.5]: not only do these new states expand our table of known particles, but their existence tests our understanding of the strong force that binds quarks together to form matter. Pentaquark states in particular had ambiguous evidence before LHCb’s breakthrough measurements, and extend our understanding of particle structure. This particle physics research breakthrough was only possible due to the VELO detector, built by the Liverpool group.

  • The first observation of rare B decays to dimuons sensitive to New Physics [3.6]: this is a “golden” channel to observe the indirect effects of new physics mechanisms and particles. It is predicted to be rare; a measurement different to the prediction would signal new particle interference. Such a breakdown would be incredibly important – the Standard Model must fail at some point, and this would show which potential new physics mechanisms could replace it. The observation demonstrates the power of indirect searches to probe the limits of our knowledge. It was only possible thanks to the VELO detector built by Liverpool and the Liverpool LHCb group were, and continue to be, instrumental in this measurement at CERN.

4. Details of the impact

Prof Shears has engaged audiences worldwide with Liverpool University’s LHCb particle physics research through art, philosophical debates, and international media. Impacts include:

  • influenced artistic practice and co-developed a touring Arts at CERN art exhibition;

  • shaped public debate and stimulated public interest in particle physics research through ‘ the world’s largest philosophy and music festival’, a Radio 4 debate and a BBC documentary;

  • created awareness and improved public understanding of LHCb research discoveries through media work that “ reached audiences of many tens of millions of people” worldwide.

4.1 Influenced artistic practice and co-developed an international Arts at CERN exhibition

Recognising the power of art in communicating abstract concepts and complex ideas, such as those found in particle physics research, Shears has been involved with international art projects through Arts at CERN since its foundation in 2009. Between 2016 and 2018, Shears played a key role in Collide International – “ a flagship foundational program for Arts at CERN” that involved Shears’ LHCb research group at Liverpool and FACT (Foundation for Art and Creative Technology) [5.1]. “ It’s vitally important that we have scientists at CERN like Prof Shears who strongly believe that interactions with artists are very useful,” says Head of Arts at CERN [5.1].

Collide International provided ten successful artists - from countries including South Korea, Colombia, and Finland - with a two-month residency at CERN to immerse themselves in particle physics research, and a one-month residency at FACT to explore ways of realising their work [5.2a]. “ *Prof Shears was involved from the very beginning of the Collide International collaboration. In fact, she was involved before this project as a scientific partner for Arts at CERN. So, when we decided to take up this collaboration with Liverpool, it was clear that involving Prof Shears was going to be very valuable for us,*” [5.1] says Head of Arts at CERN. The Collide International award is highly competitive and judged by a panel of leading gallery curators, commissioners, and scientists including Shears [5.1, 5.2a]. “ We are passionate about staying true to the science and facts that inspire artists. Prof Shears contributed greatly … to help us to understand if a proposal was feasible,” says Head of Arts at CERN [5.1].

British-Taiwanese artist Yu-Chen Wang was one of the ten artists involved in Collide International. Wang describes how Shears’ mentorship during the CERN residency was critical to her art: “ Without Professor Shears’ expertise and assistance, my understanding of particle physics, the scientific method and the way that researchers collaborate would not have been sufficient to create [my artwork] for Broken Symmetries,” [5.3]. “ Not only did Professor Shears give me a fundamental overview about how we “do” science, but she ensured that the science was always explained to me. I've tried to reflect all of the major points which came out of my conversations with Professor Shears... I think it is a major feature of my work,” says Wang [5.3].

The collaboration also had an impact upon Wang’s creative practice. “ As an artist, I am more open to different approaches and better able to link up different ideas as a result of working with Professor Shears through the Arts at CERN Collide International Award,” says Wang [5.3]. According to the Head of Arts at CERN, Shears’ “ mentorship of artists during the residencies at CERN and in Liverpool was instrumental” in the overall success of the project [5.1].

The resulting art exhibition, ‘Broken Symmetries’, showcased artworks from all ten artists that took part in Collide International. Broken Symmetries premiered at FACT in Liverpool in 2018 and received 73,464 visitors (November 2018 - March 2019), with 15,113 “ deeply engaged gallery visits[5.2a]. “ The exhibition was a huge critical and audience success,” says FACT’s Head of Development [5.2a]. “ Prof Shears was key in supporting FACT: visiting the Large Hadron Collider with FACT staff and artists; enabling us to better understand the nuances of being a researcher at CERN, so we could best support our residencies; in the selection of artists; and as a guest speaker at public programme events[5.2a]. According to a FACT report, Broken Symmetries generated significant national attention with 29 pieces of media coverage reaching over 703,000 people, including Financial Times, BBC World Service, and i newspaper [5.2b]. Shears and the partnership “ had a profound relationship on FACT’s experience at working at the intersection of art and science”, says the Head of Development at FACT [5.2a].

Broken Symmetries toured across Europe and Asia, and was attended by 199,996 visitors. It was exhibited at Centre de Cultura Contemporània de Barcelona (CCCB), Spain in 2019 (80,096 visitors), National Taiwan Museum of Fine Arts in Taichung, Taiwan in 2020 (34,146 visitors), iMAL (interactive Media Art Laboratory) in Brussels, Belgium in 2020 (1,490 visitors), and Kumu in Tallinn, Estonia in 2020 (10,800 visitors) [5.1]. The Broken Symmetries exhibition in Barcelona was “ the third most visited exhibition in CCCB’s history[5.1]. “ We were very impressed about the number of visitors that came to the exhibitions. It was quite extraordinary. We also had a great reception to the exhibition from the Spanish and Belgian media,” says Head of Arts at CERN [5.1]. Throughout the collaboration, Shears took part in public debates [5.1, 5.2a] alongside artists (including Geneva 2016, Liverpool School of Art 2017, FACT 2018) to provide insight into the particle physics concepts behind the art and Liverpool’s LHCb research.

Broken Symmetries built on a successful project in which Shears worked with artists Evelina Domnitch and Dmitri Gelfand to provide insights into particle physics for ‘No Such Thing as Gravity’ - an artwork based on Liverpool’s antimatter research. It was exhibited at FACT in 2016 (15,772 visitors) and the National Taiwan Museum of Fine Arts in 2017 [5.4a]. No Such Thing as Gravity received widespread critical acclaim across national media, with coverage on BBC Radio 3, New Scientist and The Guardian [5.4b]. No Such Thing as Gravity was described by Liverpool Echo as a “ fascinating exhibit on what we think we know about science and its possibilities” and a “ show designed to get non-scientists thinking scientifically” by New Scientist magazine [5.4b].

4.2 Shaped debate and stimulated public interest in particle physics through philosophy

By exploring particle physics concepts through rigorous philosophical debate, Shears opened up Liverpool’s LHCb research to new audiences and shaped public debate. At HowTheLightGetsIn Festival, ‘ the world's largest philosophy and music festival’ hosted by the Institute of Art and Ideas (IAI), Shears has engaged audiences with particle physics concepts from Liverpool’s LHCb research [5.5]. Shears participated in six debates with philosophers (2014, 2015, 2016), and hosted an additional four debates (2015, 2016) on subjects as diverse as whether the universe is mathematical and the role of evidence in science [5.5]. These debates were attended in-person by 3,000 people and received 121,394 views across IAI Player and YouTube [5.5]. The IAI cited two of Shears’ debates in their end of year “best of IAI TV 2016” list [5.5].

To enhance public and cultural understanding of particle physics research, Shears took part in a philosophical debate on BBC Radio 4 (2015) and provided insights from Liverpool’s LHCb research at CERN [5.6]. Hosted by Melvyn Bragg, the debate explored “ How can I know anything at all?” and was commissioned as part of the BBC’s ‘A History of Ideas’ series. The debate is available on-demand via BBC Sounds [5.6]. Shears further explored the importance of the scientific method within Liverpool’s LHCb research on a separate Radio 4 documentary about falsification (2015) which also remains available on-demand via BBC Sounds [5.6]. Based on her Radio 4 documentary on falsification, Shears co-created a short BBC animation about philosopher of science Sir Karl Popper that has been viewed 295,309 times on YouTube [5.6]. Feedback described it as “ enlightening”, “ succinct” and “ beautiful[5.6]. This animation is showcased by London’s National Portrait Gallery (1.5 million visitors per year) as recommended background visitor information for their portraits of Popper and philosopher Karl Marx [5.7].

4.3 Raised awareness and improved public understanding of Liverpool’s LHCb particle physics research breakthroughs through international press and media coverage

Shears has “ reached audiences of many tens of millions of people” worldwide during the REF period through print, radio and broadcast media interviews that have “ raised awareness and increased public understanding of a number of key LHC research discoveries[5.8]. These include antimatter (2014-2020) [3.2], LHC Run 2 re-start (2015), lepton universality (2015-2019) [3.3], and pentaquark and baryon discoveries (2017-2019) [3.4,3.5].Prof Shears’ work with journalists and the media allows the research we fund at the LHC to be better understood by our stakeholders and the public,” according to the Co-Head of Communications at STFC [5.8].

During the REF period, Shears has provided quotes used in 12 STFC press releases about major LHCb research stories and has been interviewed by numerous major journalists [5.8], generating 66 unique pieces of high-quality coverage [5.9a] across national and international print, radio and broadcast media. Major mainstream and scientific digital and print media outlets worldwide have covered Shears’ LHCb research and included quotes from her within their coverage, including New Scientist, Nature, Scientific American, Wired (UK, Italy), Engineering and Technology Magazine, Financial Times, the Independent, The Guardian, The Times, Daily Mail, Daily Mirror, Daily Express, and Buzzfeed [5.9a]. Shears “ has a profound understanding of what interests a lay audience,” according to New Scientist’s Creative Director [5.10]. “[Shears] has explained to the public all the outstanding questions that particle physics has to answer and demystified the process of discovery[5.10].

Shears has also raised awareness and increased public understanding of Liverpool’s latest research results from the LHCb experiment at CERN through radio appearances on RTÉ Radio (Ireland), LBC Radio, BBC Radio 3, BBC Radio 4, and BBC World Service [5.9a], as well as public radio stations in the US, Finland, and Mexico [5.9a]. Through broadcast media appearances, Shears has engaged television audiences with cutting-edge research developments from LHCb, including interviews on BBC Breakfast, BBC News, BBC World, ITV News, and Arte (France), as well as an appearance on a documentary for the Discovery Channel in the US [5.10b]. For STFC’s Co-Head of Communications, “ Shears really helps the public to understand particle physics research at the LHC at a deeper level,” [5.8].

The significance of Shears’ media engagement is highly regarded by journalists, editors, and producers alike, as evidenced by repeat media interviews including, BBC News, The Guardian, BBC World Service and BBC Radio 4 [5.8, 5.9a]. “ For New Scientist journalists, [Shears] is a go-to source because she can explain the physics so clearly and crucially, put it in context[5.10]. “She has an innate ability to quickly understand what a journalist is interested in, and explain her research to them in a way that they can use to tell a powerful story to their readers and the public,” says STFC’s Co-Head of Communications [5.8]. “ The BBC Science team come back to her time and time again because they find her insight and input incredibly valuable,” [5.8].

Working with the Royal Institution (October 2013 - 2020), Shears co-created and presented six short videos about major LHCb research developments including antimatter [3.2], the Standard Model [3.3], and pentaquarks [3.4], which have been viewed online 877,275 times during the REF period [5.9b]. Shears has also delivered two TED talks in Liverpool and Arendal (2014, 2016) about LHCb research into antimatter [3.2] which have been viewed 374,956 times [5.9b].

As a result of her media work being viewed as exemplary by the scientific press, Shears was approached by Nature (2018) to provide expert advice and best practice on how scientists can interact with journalists successfully [5.9c] and she is cited within STFC media training as an “ exemplar of how to marry up media work alongside continuing to do your research[5.8]. Shears continues to receive a high number of requests for interviews about particle physics research developments from LHCb. For “ particle physics research at CERN, there are three or four experts in the UK that I always direct journalists to, and Prof Shears is one of them,” according to Co-Head of Communications at STFC who states that she “ *has reached audiences of many tens of millions of people during this period as a result of her STFC media work.*” [5.8].

1. Summary of the impact

Novel silicone oil tamponades delivering improved surgical treatment of retinal detachments have been developed and commercialised, resulting in significant impacts on health and wellbeing. The products can be injected easily through fine gauge surgical needles, allowing smaller incisions, thereby minimising patient eye trauma. They also possess enhanced resistance to emulsification within the eye, reducing complications including cloudy vision, inflammation, glaucoma and retinal redetachment. Initially launched in Europe by the University of Liverpool patent licensee Fluoron GmbH, the products are now sold in approximately 40 countries and account for approximately 37% of the silicone oil tamponade market in Europe. Since end 2013, product sales globally have generated total revenue of [text removed for publication] with approximately 73,500 patients treated.

2. Underpinning research

Retinal detachment is a serious condition that without surgical treatment results in blindness. Globally, it occurs in approximately 1 in 10,000 people per annum and the only treatment is surgery. Most commonly vitreoretinal surgery is performed in which the vitreous humour is removed and replaced with a tamponade agent in order to effect retinal reattachment. In approximately 20% of cases the tamponade used is a silicone oil.

The research was conducted between March 2005 and July 2008 (with technology transfer and quality control work continuing until mid-2014) and addressed a long standing unmet need concerning the use of silicone oils (polydimethylsiloxanes – PDMS) in vitreoretinal surgery. Such oils have been used as tamponade agents since the late 1960s. Prior to the research, only two types of oil were available to surgeons, one with a viscosity of 1000mPas (millipascal-seconds) and the second with a higher viscosity of 5000mPas. The former can be injected much more rapidly into, and later removed from, the eye through fine gauge surgical needles. However it is more prone to emulsification (i.e. breakdown into small droplets) within the eye, often causing complications including cloudy vision, inflammation, glaucoma and retinal redetachment. Conversely, 5000 oil is much slower to inject and remove but less prone to emulsification. Hence, there existed an unmet need for an oil possessing both ease of injection and high resistance to emulsification. This was heightened by a trend towards using finer gauge needles in order to minimise surgical incision size and so reduce eye trauma. This trend resulted in increasing use of 1000 oil despite the higher risk of emulsification, since injection of 5000 oil through the finer needles is prohibitively slow.

The project was based in the Department of Physics in which research was designed, compositions prepared and mechanisms of emulsification within the eye studied in vitro by principal researcher and experienced surfactant chemist Dr Michael Day (Postdoctoral Research Associate). Work in the Department was supported by colloid and polymer chemist Dr Michael Garvey (then Senior Research Fellow). The project involved a multidisciplinary collaboration with the UoL Department of Clinical Engineering, St Paul’s Eye Unit (Royal Liverpool University Hospital) and the Centre For Water Soluble Polymers, Glyndwr University (Wrexham), which uniquely included all necessary expertise in surfactant and polymer chemistry, rheology, bioengineering, ophthalmology and vitreoretinal surgery. Injection speed tests and rheology measurements were performed in the Department of Clinical Engineering, UoL and the Centre for Water Soluble Polymers, Glyndwr University respectively. The team included Professor Rachel Williams (then Senior Lecturer), Department of Clinical Engineering, UoL, who provided expertise in the bioengineering of surfaces to treat retinal detachments. Expertise in vitreoretinal surgery was provided by Professor David Wong (then Consultant Vitreoretinal Surgeon, University of Hong Kong, and Honorary Professor, UoL) and Mr Theodor Stappler (then Consultant Vitreoretinal Surgeon, St Paul’s Eye Unit). Rheological expertise and access to rheological apparatus was contributed by Dr Rob English (then Senior Lecturer, Glyndwr University).

Research indicated that emulsification of silicone oil within the eye results from shear forces, arising from natural eye movements, acting at the interface between the implanted oil and the surrounding residual thin aqueous (vitreous) layer remaining after surgery [3.1 - 3.3]. These forces lead to the growth (extension) of filaments of oil from the surface, which detach to form satellite droplets that become coated (i.e. emulsified) by materials present in the aqueous layer. Emulsification therefore depends on the extensional viscosity of the oil [3.2 - 3.3]. Accordingly, an increase in extensional viscosity was achieved by addition of a high molecular weight silicone polymer to a silicone base oil, alleviating filament detachment and droplet formation [3.3]. This had the additional advantage of rendering compositions shear thinning i.e. shear viscosity decreases with increasing shear force, thereby allowing rapid injection through fine gauge surgical needles [3.4].

The resulting novel tamponades Siluron 2000 and Siluron Xtra contain a silicone (PDMS) base oil in combination with silicone (PDMS) polymer to deliver this novel combination of enhanced resistance to emulsification and rapid injection speed. Densiron Xtra, a novel heavy tamponade used to treat retinal detachments in the lower part of the eye, also incorporates this technology. The technology is covered by a UoL patent filed in May 2006 that is licensed exclusively to Fluoron [3.1].

4. Details of the impact

The University of Liverpool has developed novel silicone oil tamponades that deliver improved treatment of retinal detachments. The products can be injected easily through fine gauge surgical needles, allowing smaller incisions and thereby minimising patient eye trauma. They also possess enhanced resistance to emulsification within the eye, reducing complications including cloudy vision, inflammation, glaucoma and retinal redetachment.

The products are now sold by the University of Liverpool patent licensee Fluoron GmbH in approximately 40 countries and in Europe account for approximately 37% of the silicone oil tamponade market. Since end 2013, products sales globally have generated total revenue of [text removed for publication] with approximately 73,500 patients treated. The impacts reported are on health, wellbeing and the economy.

Product Development

The underpinning research conducted at UoL between March 2005 and July 2008 demonstrated that a silicone oil tamponade possessing a unique combination of rapid injection through fine gauge surgical needles and enhanced resistance to emulsification within the eye could be achieved by addition of a high molecular weight silicone polymer (polydimethylsiloxane – PDMS) to a base silicone (PDMS) oil, thereby addressing a long standing unmet need for such a product in vitreoretinal surgery [3.1 - 3.4]. Additionally, such compositions are chemically identical to conventional oils, greatly simplifying regulatory approval.

The technology is covered by a UoL patent filed in 2006 (WO2006/122973 – “Composition for the treatment of a detached retina and method of production thereof”; Inventors Rachel Williams, Michael Garvey, Michael Day) [3.1]. In December 2005 the technology was licensed exclusively to Fluoron GmbH (Magirus-Deutz-Strasse 10, D-89077 Ulm, Germany; contact Dr Wilfried Kugler), a leading global supplier of silicone oil tamponades, with the company agreeing to pay all future patent costs.

Following technology transfer from the UoL, Siluron 2000 (EC Certification: CE 575554) was launched by Fluoron in Europe in 2008 [5.1; 5.2]. The product has a much lower shear viscosity (approximately 2300mPas) than conventional 5000 silicone oil and (unlike the latter) is shear thinning and so can be injected approximately 3 times as rapidly as 5000 oil whilst possessing similar emulsification resistance [3.2 - 3.4].

This was followed in July 2013 by Siluron Xtra (EC Certification: CE 575554) [5.1; 5.2]. Compared to Siluron 2000, Xtra contains a higher amount of silicone polymer, increasing the extensional viscosity and therefore further enhancing resistance to emulsification [3.2 - 3.4]. The product has a shear viscosity of approximately 4600mPas and (again due to shear thinning) can be injected approximately twice as rapidly as conventional 5000 silicone oil [3.4].

A third product, Densiron Xtra, a “heavy tamponade” tailored specifically for the treatment of retinal detachments in the lower part of the eye, was launched in 2016 [5.2]. This delivers enhanced resistance to emulsification compared to other heavy tamponades (with this product more rapid injection is not advantageous since existing heavy tamponades are already easy to inject).

Economic Impact

The UoL technology is unique and distinguishes Fluoron’s products from those of competitor suppliers of standard silicone oil tamponades. By end 2013, the UoL patent had been granted in Australia, China, Hong Kong and Japan. Since end 2013, the patent has been granted in Canada (2015), the EU (2015) and Turkey (2015) and is currently pending in the USA.

Globally, the annual incidence of retinal detachments is approximately 1 in 10,000 people. In Europe there are approximately 80,000 cases per annum with approximately 20,000 being treated with a silicone oil tamponade. In 2019, combined European sales of Siluron 2000, Siluron Xtra and Densiron Xtra were approximately 7,540, indicating a market share of approximately 37% (5.3]. Globally, between end 2013 and end June 2020, combined sales of the products were 77,224 generating total revenue of [text removed for publication] (compared to total unit sales and revenue between 2008 and end 2013 of 38,736 and [text removed for publication] respectively) [5.3].

Impacts on Health and Wellbeing

The novel products have transformed the treatment of complex retinal detachments by combining the advantages of conventional silicone oil tamponades whilst alleviating the drawbacks, thereby improving patient outcomes. Between end 2013 and end June 2020, approximately 73,500 patients have been treated and therefore benefited from the technology. Testimonials from internationally leading vitreoretinal surgeons evidence benefits to health:

  • The introduction of the oils has in my mind already saved a lot of eyes from complications and costs of treating these complications… I fully endorse the invention and I regard it as one of the UK’s best contributions to the field of vitreoretinal surgery” - Consultant Vitreoretinal Surgeon (Retired), St Paul’s Eye Unit, Royal Liverpool University Hospital [5.4]

  • From a patient perspective emulsification resistance remains the paramount quality of any silicone oil since it is thought that it was precisely the emulsified droplets that give rise to postoperative ocular inflammation, glaucoma and ultimately sight loss. Herein lies the patient benefit in choosing a medical device (silicone oil) with a reduced tendency to emulsify. In essence, it is a better product” - Consultant Vitreoretinal Surgeon, Hospital Ophthalmic Jules-Gonin, Lausanne [5.5]

Prior to this research, surgeons were faced with a choice between ease of injection with a greater risk of emulsification or greater emulsification resistance but with much slower injection, with the trend towards finer gauge surgery often leading surgeons to opt for 1000 oil with the associated greater risk of emulsification-related complications such as impaired vision, inflammation, glaucoma and retinal redetachment. With Siluron 2000 and Siluron Xtra, rapid injection offers shorter operating times and compatibility with finer gauge surgical needles, the latter allowing for smaller surgical incisions, thereby minimising patient eye trauma; enhanced emulsification resistance reduces the risk of patients suffering post-operative complications, thereby reducing the likelihood of further treatment being required and hence reducing costs to (for example) the NHS and improving patient wellbeing. Testimonials from Clinicians within the NHS have described the impact on their practice:

  • Before the launch of Siluron 2000 and Siluron Xtra I was using 1000 centistoke oil but have now switched to Siluron 2000 where I want a light (i.e. buoyant) oil and Densiron Xtra for situations where I want to use a heavy oil… I have found a low incidence of emulsification, significantly improved compared to the previous oils…The ability to inject and extract the oils even with 25 gauge surgery is also much improved compared to high viscosity oils… Siluron 2000 and Siluron Xtra have been major advances for vitreoretinal surgery” - Consultant Ophthalmologist, Sunderland Eye Infirmary [5.6]

  • Vitreoretinal surgeons aim to remove the silicone oil after 3 months because of the risk of emulsification leading to complications with keratopathy, disease of the cornea and glaucoma… in my experience such complications have been much less with Siluron 2000 and Siluron Xtra” - Consultant Vitreoretinal Surgeon, St Paul’s Eye Unit, Royal Liverpool University Hospital [5.7]

The efficacy of the products has been confirmed in reported studies. Stalmans et al (72 patient study, 2015) reported that Siluron 2000 could be injected and removed significantly more rapidly than standard 5000 oil and showed similar emulsification behaviour [5.8]. Hussain et al (28 patients, 2017) concluded that Siluron Xtra “seems to be an acceptable alternative tamponade for the management of complex retinal detachments with comparable anatomical success… to other low viscosity silicone oil agents but more importantly with a lower rate of emulsified oil-related complications” [5.9]. An in-vitro study by Chan et al (2017) reported that Siluron 2000 emulsified less than a viscosity-matched standard 2000 oil and Siluron Xtra emulsified less than standard 5000 oil [5.10].

In summary, the novel silicone oil tamponades have had a significant impact on patient outcomes with health benefits including reduced eye trauma and reduced post-operative complications. In Europe, the products have achieved approximately 37% share of the silicone oil tamponade market. The products have had global reach through sales in approximately 40 countries, generating total revenue of [text removed for publication] and being used to treat approximately 73,500 patients.

1. Summary of the impact

AIMES Grid Services Ltd. was founded in 2005 on the basis of Liverpool’s particle physics research and the IP generated by Liverpool in the development of the MAP2 computer for CERN. Since 2014, AIMES has generated economic and healthcare impacts that include:

  • Increasing the company’s annual turnover by 96% to £4.5M in 2019/20, significantly exceeding the UK’s national average turnover for small companies, and creating 21 new jobs, representing a 70% increase in the company’s headcount

  • Contributing to the improvement of health service design and commissioning through its data centre and the deployment of Trustworthy Research Environments (TREs) in 2016

  • Delivering improvements for NHS cost and resource efficiency through the use of TREs

2. Underpinning research

2.1 Construction of MAP1 and MAP2 computers for CERN at the University of Liverpool

At the end of the 20th century, the computing infrastructure at CERN required to support its next generation of particle physics experiments represented a formidable challenge. In 2000, this challenge was partially addressed by the University of Liverpool through the construction of Europe’s first commodity off-the-shelf computer – MAP1 in Liverpool’s Department of Physics.

MAP1’s novel architecture incorporated high-density packing of computing hardware whilst enabling easy access and efficient cooling. MAP1 enabled the creation of a grid of low-cost computer centres with a huge compute cycle capability and was, in part, a catalyst for the £120M UK e-Science programme in late 2000.

In 2003, as part of e-Science programme developments, Bowcock’s research team at Liverpool was awarded a Science Research Investment Fund grant of £1.3M to further develop MAP1 into MAP2, which was commissioned in 2003. MAP2 comprised of 940 computation nodes, 100 terabytes disc space and had 30 times the computing power of MAP1. In November 2003, MAP2 was ranked as the 22nd most powerful academic computer in the world and the 86th most powerful computer worldwide .

The benefits of MAP2 compared to MAP1, included:

  • Improved (custom) Flow Control Software (FCS) enabling the integration of many thousands of PC’s. Software included queue management and system maintenance.

  • Use of a centralised telecommunications grade network switch (Force10) with over 100’s of additional commodity switches compared to MAP1. This design and architecture was incorporated in the LHCb particle physics experiment at CERN.

2.2 Application of Liverpool’s MAP2 computer to research at CERN’s LHCb experiment

MAP2’s original scientific purpose was to design a revised Vertex Locator (VELO) detector for the LHCb experiment at CERN [3.1], as well as for processing in condensed matter physics [3.2]. MAP2 facilitated detailed optimisation studies into the VELO detector geometry layout and detector strip resolution, as well as investigations into optimum thickness of support structures. From 2010-2018, LHCb relied on the VELO modules for its primary tracking [3.3] (Bowcock, Shears, et al.). MAP2 was used to underpin other essential aspects of particle physics experiments such as providing the CPU requirements of full event simulation for the ATLAS and LHCb experiments at CERN [3.3, 3.4, 3.5], including the trigger design of LHCb [3.3, 3.4, 3.6].

2.3 Establishment of AIMES Centre to assist SMEs with computing technology adoption

MAP2 demonstrated that - using its software and networking stack, and mechanical and cooling configuration - it was possible to create world-class computing facilities for private sector organisations. This level of computing technology had previously been out of reach for SMEs and many large companies. Time-to-solution for computing technology was a significant problem for UK industry in the early 2000s. This was recognised by the North West Development Agency (NWDA) and the European Commission as the technical justification for funding the formation of the Advanced Internet Methods and Emergent Systems ( AIMES) Centre.

The AIMES Centre was established as a collaboration at Liverpool between the Department of Physics and the Management School, and secured funding of £7.8M (£2M from ERDF, £5.8M from NWDA) in 2003. Bowcock was the founding Technical Director of the Centre. The AIMES Centre focussed on assisting SMEs with the adoption of new computing technology and on creating business start-ups capable of exploiting new markets. Its objectives included the optimisation of supply chains within the automotive and aerospace sectors, as well as the optimisation of intensive care resources and delivery of care for Alder Hey Children’s Hospital.

2.4 Formation of AIMES Grid Services Ltd and development of Trustworthy Research Environments for the healthcare sector

In 2005, the AIMES Centre became a standalone commercial operation and was renamed AIMES Grid Services Ltd. In 2012, AIMES developed the Health Cloud – a dedicated virtual environment that enables NHS Trusts to use cloud computing technologies and manage sensitive data in a secure governed environment. In 2016, AIMES extended its Health Cloud capability to create digital infrastructures known as Trustworthy Research Environments (TREs) – secure platforms, where sensitive health data can be ingested.

The TRE provides a secure, computational powerful and stable platform to store, access and analyse confidential data. Importantly, it also meets common data standards, information governance and legal requirements for the storage and use of health data, which allows users to perform detailed data analysis using bespoke analytics tools. Without the TRE, data analysts will have no other choice but to download a snapshot of some data on their own local hard drives; this can be risky and insecure due to data confidentiality; data volumes can be large, change quickly and be out of date very soon after.

The development of the TRE infrastructure by AIMES builds upon the original research work undertaken by the University of Liverpool’s Particle Physics group in three important areas :

  • Research and technical expertise required to build cloud-based high-performance computing services. The first AIMES cluster was the MAP2 computer system at Liverpool and facilities were part-funded by AIMES Grid Services.

  • Technical expertise required to deploy commercial applications on AIMES’ facilities. Washbrook from Liverpool’s Particle Physics group was employed by AIMES and utilised the MAP2 middleware for the deployment of commercial cloud services.

  • Data science expertise required to analyse and compute large data sets. This collaboration continued with the input of Liverpool particle physicists who supported the development of hospital episode data analysis and geo-mapping against population changes.

4. Details of the impact

Founded on the basis of and underpinned by Liverpool University’s particle physics research and IP, AIMES has generated economic and healthcare impacts since 2014 that include:

  • Increased the company’s annual turnover by 96% to £4.5M in 2019/20, significantly exceeding the UK’s national average turnover for small companies, and created 21 new jobs

  • Contributed to the improvement of health service design and commissioning through its data centre and deployment of Trustworthy Research Environments (TREs) in 2016

  • Delivered improvements for NHS cost and resource efficiency through the use of TREs

4.1 Economic impact of AIMES – increased revenue generation and new job creation

Since its foundation based on and underpinned by Liverpool’s particle physics research, AIMES has developed into an award-winning and industry-leading commercial data centre service provider based in the Liverpool City Region. Securing £1M Development Funding from Santander in May 2018 allowed AIMES to create a new 10,000 sq. ft. Health Informatics Centre at Kilby House Facility in Liverpool [5.1]. The new centre provides state-of-the art digital accommodation, specifically designed for advanced health informatics with connections to the Kilby House data centre and to the new Health and Social Care Network.

The annual turnover of AIMES increased by £2.2M (96%) to £4.5M in 2019/20 from £2.3M in 2014/15 [5.1], underlining the economic impact of AIMES which was founded on the basis of and underpinned by Liverpool’s research. This is an average year-on-year growth of more than 14% [5.1], significantly exceeding the UK’s national average turnover figures for small UK companies with 10-49 employees of £3M per annum, as outlined by the UK government’s Department for Business, Energy & Industrial Strategy (BEIS) in 2019 [5.2]. Between 2014 and 2020, AIMES created 21 new jobs in the Liverpool City Region, bringing its current headcount up to a total of 30 staff employed [5.1]. This represents a significant increase of 70% from 2014 to 2020, and demonstrates the growth and viability of AIMES Grid Services’ business.

4.2 Healthcare impact of TREs – improved health service design and commissioning

In the healthcare sector, when dataflows cross organisational boundaries, including the NHS, social care, universities, police and industry, there is a need for a trustworthy infrastructure to link data while preserving the needs of the data owners, citizens, and researchers. AIMES Grid Services took on the task of addressing this challenge by using research expertise from the Department of Physics’ MAP2 computer to develop the Trustworthy Research Environment (TRE) - a secure platform to analyse data and satisfy common data standards, information governance and legal requirements for the storage and use of data.

In 2016 AIMES Grid Services pioneered the TRE infrastructure in a number of project initiatives in collaboration with industry, the NHS and universities. AIMES’ digital services have had significant impact on improving the design and commissioning of healthcare services in the North of England through the Connected Health Cities programme. Three examples of the impact of TREs on healthcare services (4.2a, 4.2b, 4.2c) are described below.

4.2a The Connected Health Cities programme – “ Healthcare Project of the Year

AIMES Grid Services was awarded a contract to host the infrastructure for the Connected Health Cities programme to unite regional health data with advanced technology. AIMES used its cloud computing expertise to build two TREs: the North West Coast, and the North East and North Cumbria TREs which enabled local adaptation to governance, data and research requirements [5.3]. The pan-northern Connected Health Cities programme was named “ Healthcare Project of the Year” at the 2018 Bionow Awards [5.4], recognising Connected Health Cities’ innovative use of TRE technology and NHS data in creating and embedding learning health systems across 20 care pathway projects in the North of England. “The key element in selecting the winner was that through bringing together a complex number of partners and organisations, the project has been able to harness and make use of clinical data. It is a project of magnitude and truly connects the North.” - Technology Director at Trustech [5.4].

4.2b Design and commissioning of healthcare services in the North of England

AIMES’ deployment of a TRE with the Connected Health Cities programme was pivotal in improving the design and commissioning of healthcare services in the North of England.

The Great North Care Record created one shared care record for patients. Using the TRE infrastructure, the Great North Care Record now gives care records access to 100% of General Practices across the North East and North Cumbria, involving 400 practices, 25 NHS and Local Authorities, and 12 NHS Clinical Commissioning Groups, saving at least £8M per year [5.3].

By running newly developed algorithms on the TRE infrastructure, an extra 66% of epilepsy-related admissions were identified when compared to just using the primary diagnosis code, capturing more accurate average length of stay [5.3]. An application of these findings enabled paramedics to access epilepsy care records from secondary care to inform decisions about conveyance and immediate care [5.3]. “ By making additional information accessible for our ambulance clinicians, they will be able to make more informed decisions based on the patient’s medical history. This means that if the patient could benefit more from care in the community, unnecessary A&E admissions can be avoided which in turn will free up vital emergency resources.” - Chief Consultant Paramedic, North West Ambulance Service NHS Trust [5.3].

4.2c Detecting cases of Alcohol-Related Liver Disease

The North West region of England has one of the country’s highest rates of alcohol-specific deaths and Alcohol-Related Liver Disease is the dominant cause. Early inpatient intervention has the potential to save lives, however, reports show fewer than half of patients received ‘good care’ and mortality rates are high [5.5]. Using the TRE infrastructure through the Connected Health Cities programme, an extra 40% of cases of Alcohol-Related Liver Disease were detected when compared with standard approaches for capturing data on emergency admissions. The detection of extra cases of Alcohol-Related Liver Disease resulted in improved knowledge of disease burden and better monitoring of inpatient and post-discharge outcomes [5.3].Our goal is to link, analyse and visualise data in ways that reflect the complexities of alcohol-related conditions and the wide variability in local service provision and organisation across the region – bringing local context to the interrogation of data” - Consultant Gastroenterologist at Aintree University Hospital, North Mersey HIS and Connected Health Cities Clinical Lead for Alcohol [5.6].

4.3 Impact of TREs on NHS practice and operations – improved cost and resource efficiency for health services

Current practice in large-scale, multi-centre clinical trials are often wasteful, resulting in significant costs and overheads. Trial protocols, staff records, training and governance information are typically maintained by participant sites in paper form which is not efficient practice within NHS operations. Poor recruitment for clinical trials can not only have financial ramifications, owing to increased time and resources being spent, but can also adversely influence the clinical impact of a study if it becomes underpowered [5.7].

In response to this problem, AIMES and the Liverpool Heart and Chest Hospital NHS Foundation Trust partnered to design and build a secure cloud-based platform, a TRE called “Streamline”, to manage research data capture and document workflows. The benefits of Streamline include: reduced administration costs to keep protocols up to date, increased visibility of the research data for adaptive trial designs, easier data collection for medical professionals, making clinical trials paper-free and guaranteeing failsafe access to current documents and legacy versions, appropriate access from any web-enabled device, allowing remote-view and monitoring of research governance, for cost efficiency and assurance.

Streamline enabled a reduction of almost 50% in the time taken to recruit patients into cardiac clinical trial programmes at the Liverpool Heart and Chest Hospital NHS Foundation Trust. When first deployed, a three-year recruitment target was met within 18 months [5.1]. “The online trial system is a sea-change in trial governance. It relieves individual trial staff of the burden of site file management and provides many useful tools to the system administrators” - Research IT and Systems Lead at the Liverpool Heart and Chest Hospital NHS Foundation Trust [5.7].

Having worked together in the deployment and implementation of TREs, the partnership between AIMES Grid Services and the Liverpool Heart and Chest Hospital NHS Foundation Trust was one of the three finalists for the “ Best Industry Partnership” award at the North West Coast Research & Innovation Awards 2017 [5.8], recognising the significant impact of their partnership on cost and resource efficiencies in the provision of healthcare services for the NHS.
